[Spca50x-devs] AIPTEK 1.3 Megapixel Mini PenCam (AKA MegaCam)

[Paul B. <pb...@ly...>]

Hello, guys!

I've picked up this cute tiny toy, camera as long as my index finger
which supports up to 1248x960 still images and 624x480 video.

Of course the problem is that it is not supported yet. Is someone
working on this? I'd like to get in touch.

Vendor Id:  0x04fc
Product Id: 0x504a

DSP is Sunplus SPCA504A-P3 (verified by carefully popping open this
piece of craftmanship :) )

Sensor (I THINK!) is OmniVision's OV9620. Yes, I did look at the sensor
as well, but could not find any markings. What makes me think that it is
OV9620 is that they proudly announce (on their press releases page) 
support for this 1.3M CMOS sensor from Sunplus' SPCA504A.

By the way, http://spca50x.sourceforge.net/ lists 
spca508 OV6620 Fair spca508a is treated as 508,
but I could not find in current CVS code any references to any OV
sensors!
Am I missing something or was support pulled off because of some NDA 
nastiness on OV part?

I've tried to put this Vendor/Product IDs in all 'case' statements in
spca50x_probe() in turn, naturally nothing worked. I've got all sorts of

usb_control/bulk_msg: timeout
drivers/usb/spca50x.c: reg write: error -110
drivers/usb/spca50x.c: [spca50x_write_vector:913] Register write failed
for 0x3,0x20,0x3
drivers/usb/spca50x.c: Failed to configure camera

except when I pretended that it is a ViewQuest camera, in this case
the behaviour was a bit more interesting: after timeouts it did 
manage to read some information back:

Anyway, please let me know if anyone is interested in hacking this 
little thing or if I should just drive back to BestBuy and return it?
By the way, the BestBuy price was $99, I thought it is pretty good for
something which goes to that resolution.
